I'm not sure this is what you want. Type::Smi denotes a value that can be stored
as a Smi, i.e. a number in int31/int32 range (depending on platform). It is
therefore not the same as HType's "IsNonPrimitive() || IsJSObject()". I think
I'd prefer an explicit union of Types instead (likely just Receiver, Undefined).

   V(Detectable,      kAllocated - kUndetectable)
 
 #define TYPE_LIST(V)     \
